Answer

PSLE 2017 Paper 2 Q13 

2u = 3850 – 2030 = 1820

1u = 1820/2 = 910

2030 +910 = 2940 (a)

Gopal 3u = 2940

Gopal 1u = 2940 /3 = 980
Henry 1u = 910

(980-910)/5 = 14 days

3u  = 14 x 3 = 42 days (b)

(a)
3850 – 2030 = 1820
1820/2 = 910
910 + 2030 = 2940

(b)
Method 1 :
910 x 3= 2730
2940 – 2730 = 210
210/5 = 42

Method 2 :
number of days Gopal worked : 3u
number of days Henry worked : 1u
amount Gopal was paid per day : 1p + 5
amount Henry was paid per day : 1p
3u x (1p + 5) = 3up + 15u ——-> 2940
1u x 1p = 1up ——-> 910
3 x 910 + 15u = 2730 + 15u ——-> 2940
1u ——-> (2940 – 2730)/15 = 14
3u ——-> 14 x 3 = 42

Ans : (a) $2940; (b) 42 days.
